(Set 4)
TOPICS: SCIENCE &
TECHNOLOGY,ENVIRONMENT
1)What is
the 3D Printing ?
Ans:
1)3D printing, also known as additive
manufacturing, is a process by which physical objects are created by depositing
materials in layers based on a digital model. All 3D printing processes require
software, hardware and materials to work together.
2)3D printing technology can be used to
create everything from prototypes and simple parts to highly technical final
products such as aeroplane parts (US
site), eco-friendly buildings, life-saving medical implants and even
artificial organs using layers of human cells.
2) “India primarily imports thermal coal
from South Africa and Indonesia, and average prices from these countries
decreased by approximately 54% and 38% respectively during April 2023 to
January 2024, compared to the corresponding period in the previous year.” What are the reasons ?
Ans
:
Imports are
also driven by higher-grade requirements in some sectors such as cement which
require coal of higher GCV value for clinker production; however, as supplies
of high-grade coal in India are largely limited, it has led to cement plants
largely looking towards imports for its usage. The cement industry is also a
major importer of pet-coke
In this
connection, consider the following
reasons :
1) Less
availability of domestic coal (due to challenges in developing coal mines
related to land acquisition, delay on obtaining statutory clearance etc and
logistics constraints for evacuation) against the demand of coal in country or
GDP growth of the country.
2) Low
quality of coal as per demand e.g. coking coal required for steel sector.
3) Pricing of
coal in international market. Several studies (like PWC research) 11suggest
that the International coal price and Coal imports to India are inter-linked.
4)To
establish the correlation the committee has studied the last 10-year coal
imports both for Coking and NonCoking data along with average International
coal prices.
5) Bulk of
the coal in the country is imported by the Non-Regulated Sector (NRS). NRS coal
consumers mostly procure their domestic coal requirement through participation
in the NRS linkage auctions conducted by Coal India Limited. NRS linkage
auctions are mine specific. Successful participation in these linkage auctions
provides the NRS consumers an assured source of coal supplies, say for an
initial tenure of 5 years / 10 years. However, at times when the international
coal prices are low, NRS coal consumers tend to exit from the Fuel Supply
Agreements executed with the coal companies and import coal to meet their
requirements, leading to supply chain disruptions
=================================================
3) What is
the ground breaking project to harness
geothermal energy for power generation undertaken by Ministry of Coal ?
Ans:

joint initiative i.e Krishi Sakhis Training Programme to certify 70,000 Krishi
Sakhis as “Para-Extension Workers” was launched.
Being local, knowing the local language, culture,
practices and having undergone all the joy and sorrow together with the
villagers and farmers, they understand the ecosystem better. Krishi Sakhis,
most of them farmers themselves understand better and are in an advantageous
position to explain to their friends, families, villages in a more relatable
manner.
They act as key resources, guiding farmers
to access the benefits of these initiatives. They would carry out
awareness generation meetings on Natural Farming, Soil health Management and
Testing as part of Janbhagidari. These initiatives will have a direct impact on
increasing the livelihood of the Krishi Sakhis and ensure wider reach for the
agriculture programme and schemes. Till date close to 3500 Krishi Sakhis
have already been trained and the program is being simultaneously implemented
in 13 states

29) “The
difference blood groups pose a serious hurdle in the easy availability of blood
for transfusion, which always seems to be in short supply.” What are the research efforts in the area of blood groups and blood for transfusion ?
Ans :
1) Austrian
biologist Karl Landsteiner discovered human blood groups, that blood
transfusions became safer. Landsteiner’s work made it possible to determine
blood types and thus paved the way for blood transfusions to be carried out
safely. For this discovery he was awarded the Nobel Prize in Physiology or
Medicine in 1930.
2) The
differences in human blood are due to the presence or absence of certain
protein molecules called antigens and antibodies. The antigens are located on
the surface of the red blood cells and the antibodies are in the blood plasma.
Individuals have different types and combinations of these molecules. The blood
group one belongs to depends on what one has inherited from one’s parents
3). But a
recent finding of a research team in Denmark may change all that. An
international team led by Henrik Clausen of the University of Copenhagen in
Denmark has discovered two novel enzymes in bacteria that can efficiently
convert blood groups A, B and AB into the ‘universal’ O group.
===========================================
Question: 30)
Bio-fertilisers are not only eco-friendly and cost-effective but also
help increase production and productivity of various pulse crops. Explain about
Bio-fertilizers ?
Ans :
Biofertilisers
are also easily available at various research institutes at low cost
Use of bio
fertilisers such as Rhizobium, Azospirillum, phosphate solubilising bacteria
(PSB) and Trichoderma has also resulted in significant increase in all growth
and yield parameters in pulse crops.
Apart from
this it has a potential role in saving of chemical fertilisers in pulse crops
cultivation.
Biofertilisers
such as PSB and mycorrhiza fungi significantly increase the yield and
phosphorus content in pulse crop.
Similarly,
the growth attributes and nutrient uptake in pulse crops also increased due to
application of Rhizobium, PSB, Azotobacter and Azospirillum compared to control
The method
of application is easy and simple in pulse crops production.
